Summary:To provide a torque converter for an electrically-driven vehicle capable of reducing power loss caused by a sliding of an electrically-driven vehicle at the time of its starting and securing a requisite driving power at the time of high load.SOLUTION: In a torque converter 1 for an electrically-driven vehicle constituted such that a pump impeller 2 connected to an input shaft 32 and a turbine runner 3 connected to an output shaft 33 are oppositely arranged, a stator 4 is arranged among these pump impeller 2 and the turbine runner 3 and a lock-up clutch 9 directly connecting the input shaft 32 and the output shaft 33 under a predetermined condition by being turned ON/OFF by hydraulic fluid pressure and a damper mechanism 8 arranged between the turbine runner 3 and the output shaft 33 are provided, there are provided a spring (a pressure applying mechanism) 27 for turning ON the lock-up clutch 9 at a low torque state where an electric vehicle starts to move, and a releasing mechanism for turning OFF the lock-up clutch 9 kept in ON state in response to a transmittance torque.SELECTED DRAWING: Figure 2 【課題】電動車両の発進時の滑りによる動力損失の低減と高負荷時における必要な駆動力の確保との両立を実現することができる電動車両用トルクコンバータを提供すること。【解決手段】入力軸３２に接続されたポンプインペラ２と出力軸３３に接続されたタービンランナ３を対向させて配置し、これらのポンプインペラ２とタービンランナ３との間にステータ４を配置するとともに、作動油圧によってＯＮ／ＯＦＦして所定の条件下において入力軸３２と出力軸３３とを直結するロックアップクラッチ９と、タービンランナ３と出力軸３３との間に設けられたダンパー機構８を設けて構成される電動車両用トルクコンバータ１において、電動車両が発進する低トルク時においてロックアップクラッチ９をＯＮさせるスプリング（与圧機構）２７と、ＯＮ状態にあるロックアップクラッチ９を伝達トルクに応じてＯＦＦさせる解除機構と、を設ける。【選択図】図２
